Submersible Sewage Pump Controllers

Technical Data: 

Designed to control and protect pumping systems electronically;
• Control and Proteciton of multiple pumps
• Incorporated Standart PC-ST3-V2 Relay
• Level control over float switches
• Over heat protection
• Sequential run
• Phase order and failure protection
• Flood level warning
• Safety switch on door
• Manual-Automatic operating modes as standard (optional on single pump systems)
• ABS polycarbonate or Metal case

Design Features: 

Standart PCST3-V2 Motor Protection and Control Relay is an indispensible part of submersible sewage pump controllers. Its integrated features provides high Reliability and Safety of your pumping system.

Standart PCST3-V2 Motor Protection and Control Relay
When the device is switched on, all indicator lights sequentially blinks and control unit makes a self-check. If there is no failure, NORMAL indicator light blinks in yellow to indicate the motor is ready to start.
OVER HEAT
In the event of overheating of motor windings, in which the temperature exceeds 130°C, the red indicator light switches on and the relay shuts down the motor. Indicator light blinks in short periods at alarming position. When motor has cooled down, relay restarts the motor while alarming goes on until the RESET button is pressed. Pressing the RESET button disables the alarm relay and indicator light stops blinking.
WATER LEAKAGE
In case of water leakage into the motor casing or oil chamber, red indicator light switches on and the relay shuts down the motor. Alarm relay becomes activated and until the RESET button is pressed, alarming goes on by blinking of red indicator light in short periods. When this failure occurs, the pump needs to be overhauled.
MAX LEVEL
When water level reaches the maximum level, which is set by the user, float switch sends on alarm signal and yellow indicator light starts blinking. This alarm does not affect the current state (run or stop) of the pump. Pressing the RESET button disables the alarm relay and indicator light stops blinking.
PHASE FAILURE
An external phase protection relay, mounted in the control panel, is connected to PCST3-V2 for checking phase sequence and phase failures. When there is a failure in mains voltage or in phase sequence, the motor is shut down by the relay and red indicator light starts blinking. By the time the failure is fixed, the motor restarts automatically while alarming goes on until the RESET button is pressed.
OVERLOAD
The relay shuts down the motor, if the current overload limit is exceeded. Meanwhile, alarm relay becomes activated and red indicator light starts blinking. As the failure is fixed, pressing the RESET button will disable the overload and the alarm relay, so the system turns back to normal conditions.
NORMAL
By the time all red indicator lights on PCST3-V2 switch off, green indicator light switches on, meaning that it is ready to run the motor. In case of failure, green indicator light switches off and the relay shuts down the motor.
